Please dude, not more than a year ago, Benteke was a decent striker for Genk, who forced his way to the Premier League threatening to end his contract if they wouldn't let him. Not many people thought he would succeed. Until then, Lukaku was BY FAR the biggest prospect of the two, being two years younger as well. Benteke proved the critics wrong. But last year, they were evenly matched. If both play regularly, it will be a very hard decision for the trainer, since they are almost identical. Benteke has slightly better link up play, Lukaku has slightly higher speed and strength.
